Every item I mentioned in this comment can be sold on the AH for various prices, which can be high since they are hard to get.

Good luck!

Still valid post-Cata. DO NOT destroy or vendor it, as it can be used 1-2x to get the main quest to kill Terokk (see above post for links). It goes with the other three trophy items and is important for those trying to grind Sha'tari reputation. AH is always an option if it isn't needed. =^)
